note: 358122

I was looking thru a couple of notes and i was stuck with a certain statement which I could not comprehend. Would you share some light on this?

=============================================

Note: 358122

Since 4.6C, if a check indicator does not exist, a check indicator with the value "Not maintained" is entered in table TCDCOUPLES via a trace function in SAP systems (transport/systemtype = SAP) and in customer systems when the authorization trace is switched on (auth/authorization_trace = Y) when running ABAP statement CALL TRANSACTION.

Only when the check indicator (TCDCOUPLES-OKFLAG) is set to "check" does the system check through the kernel for CALL TRANSACTION.

=============================================

From what I understand, CALL TRANSACTION does not check for S_Tcode for the called transaction. When the field OKFLAG in the table TCDCOUPLES is set tp "Check" then the system would explicitly check for the called transaction in S_TCODE.
